摘　　要：通过对糯扎渡水电站心墙堆石坝进行大量防渗土料掺入人工砾石的试验,研究不同掺砾比例下掺砾土料的各种工程特性,寻求该工程防渗土料要求的掺砾比例。研究成果表明,掺砾土料砾石含量宜控制在30%～40%左右。Through tests on impervious soils with artificial gravel mixed for the cutoff wall of Nuozhadu Hydropower Project, the engineer- ing characteristics of the soils with gravel mixed at different gravel-mixed proportions are studied to seek the gravel-mixed proportions re- quired by soils. The study shows that the gravel content in the soils with gravel mixed should be controlled at 30% - 40% approximately.
